CHIMNEY-TOP.

SPECIFICATION forming part of Letters PatentNo. 363,778, dated May 24, 1887.

Application filed March 19, 1887. Serial No. 231,574. (No model.)

To aZZ whom it may concern.-

Be it known that l, GEORGE TURNER, a citizen of the United States, residing at Schuylers Lake, in the county of Otsego and State of New York, have invented new and useful Improvements in Chimney-Tops, of which the following is a specification.

This invention relates to improvements in chimneys, referring more particularly to the formation of the tops thereof, its objectsbeing to prevent the upper layers or tiers of brick from being displaced or broken and disfiguring or injuring the chimney thereby.

The invention consists in the construction and novel arrangement of a top embracing the upper end of the chimney, as hereinafter described, pointed out in the appended claims, and illustrated in the drawings.

In the accompanying drawings, Figure 1 represents a perspective view of a chimney having the improved top attached. Fig. 2 represents a vertical section on the line 00 m of Fig. 1. Fig. 3 represents a vertical section on the line g y of Fig. 1. Fig. 4 represents a detail sectional view showing how the small corneroffsets at the lower part of the top are inserted into the brick-work.

Referring to the drawings by letter, A designates a chimney, and B the top or casing, preferably of cast metal, secured upon the upper end thereof. Thesaid casing consists of the four similar side pieces, 0, and the top plate,D. The side pieces are beveled at their corners at angles of forty-five degrees, and secured together, to form a rectangular frame, E, having the circumferential depending flange e. the tops of the corners formed by the flange e the frame F is provided with the offsets c, triangularin plan view, which enter corresponding recesses in the brick-work of the chimney. Above the flange c the frame extends horizontally outward at f, and then rises vertically about the height ofa brick at F. It then eX- tends again horizontally outward at g and again vertically upward at G, but not quite so high as before. part G the platcl) is laid, and bolts (1 d passed through openings therein and in the part 9 of the frame and the nuts (1 screwed thereon below said part 9. The upper ends of said openings in plate D are countersunk, so that Upon the upper edge of the.

the heads of the bolts (1 d are flush with the upper surface of the plate, and the said surface is inclined downward from its central rectangular opening, h, to cause rain to run off its outer edge.

- H is a flange that extends downwardly vertically from the opening, h and surrounds the same, and I is a cover semicircular in crosssection and attached over the opening h, to prevent rain,snow,or hail from falling therein.

The top extends outward on all sides some' what beyond the frame, and is provided with a circumferential depending flange, z, to prevent water from entering.

In building the top of the chimney the same is inclosed by the frame E, the small triangular flanges being inserted into corresponding recesses in the brick-work at the lower surface of the second tier of brick from the top.

The highest tier of brick is set suflieiently outward for the flange H to rest against its inner surface flush with the interior surface of the chimney below the top.

The top, as described, is ofsimple construction, and when secured to the upper end of the chimney will form a strong union therewith, as the small triangular flanges enter rccesses in and are supported by the brick-work, and the top of the upper tier of brick supports the top plate, D. The frame E, moreover, cannot bind upon the chimney by contraction, as its interior does not fit closely thereon, the chimney'top being supported or held to the chimney, as described.

Having thus described my invention, I claim- 1. The herein-described chimneytop, con sisting of four side pieces connected at their ends to form a rectangular frame, and a top plate secured to the upper edge of said frame, the frame being provided with a circumferential depending flange to flt upon the outside of the chimney, smalltriangularoffsets within the corners of the depending flange adapted to enter corresponding recesses in the brickwork and a circumferential horizontal portion above said flange, and the top being provided with a flange depending from its central rectangular opening to enter and lie against the interior of the chimney, and being connected to the frame by bolts which pass through suitable openings in the plate and in the horizontal portion of the frame and are engaged by nuts below the latter, substantially as specified.

2. The combination, with a chimney, of the rectangular frame E, provided with the flange e, the offsets e, entering corresponding recesses in the brick-work, and the horizontal portion g, having bolt-openings at its corners, the top plate provided with the chimney h, the flange i, and the flange H, to enter theinterior of the chimney, and the bolts d d, which pass through countersunk openings in the plate and boltopenings in the part 9 of the frame and are engaged to nuts below said part, substantially as specified.

3. The combination, with a chimneyhaving its highestlayer or tier of brick set a sufficient distance outward from the adjacentlayer or tier, of the plate D, having a central'opening,

h, and a flange depending therefrom and lying 20 against the inner surface of the first layer of brick, so as to be flush with the second layer thereof, and inclining downward on all sides from its central opening, the frame E, provided with the flange e, offsets e, and the horizontal 25 portion 9, substantiallyasdescribed, and connected to the top plate by bolts, and the cover attached to the top plate and standing over the opening therein, substantially as specified.

In testimony that I claim the foregoing as 30 my own I have hereto afiixed my signature in presence of two witnesses.

GEORGE TURNER.
